How do I save a log of OpenGL calls?

I want to save all the OpenGL calls that an application is making. An HTML log is mentioned and I set various relevant options, but I have no idea where that is or if it's even saved. If I pause the program I see the call history window, but I can't save anything from there, just copy a single call as text. The data is there, I just want to save it. How do I do that?
